This application sought Registered Building consent for the installation of replacement windows at Derby House, 7 Castle Street, Castletown — a two-storey traditional stone building, formerly a post office, located opposite Castle Rushen and adjoining the Police Station. The application was made in association with a related planning application. The building is notable for its timber sliding sash windows with Georgian glazing bars and two prominent chimney stacks. The key planning issues considered were the potential impact on the character and appearance of the Registered Building and the Conservation Area, as well as the effect on the wider street scene. The application was approved on 9 October 2015 under delegated authority, subject to three conditions. The officer's recommendation was also to permit the works.
The application was approved by the Head of Development Management under delegated authority. The key planning considerations were the impact of the replacement windows on the character and appearance of the Registered Building and the Conservation Area, and the effect on the street scene. The proposal was found acceptable on both counts.

the application conforms to the basis of the relevant aforementioned planning policies
POLICY RB/5 ALTERATIONS AND EXTENSIONS In considering whether to grant planning approval for development which affects a registered building or its setting and in considering whether to grant registered building consent for any works, the Department shall have special regard to the desirability of preserving the building or its setting or any features of special architectural or historic interest which it possesses. Registered building consent is required for the building's alteration in any way which would affect its special architectural or historic character. There will be a general presumption against alteration or extension of registered buildings, except where a convincing case can be made, against the criteria set out in this section, for such proposals. Applicants for registered building consent for alteration or extension to a registered building must be able to justify their proposals. They will be required to show why the works which would affect the character of the registered building are desirable or necessary and they should provide full information to enable the Department to assess the likely impact of their proposals on the special architectural or historic interest of the building and on its setting. Where registered buildings are the subject of successive applications for alteration or extension, consideration will also be given to the cumulative affect upon the building's special interest as a result of several minor works which may individually seem of little consequence.
